What's going on with my beardies digestive system?

[ThatAwkwardkid]

So my bearded dragon has been pooping and it's only been a little bit at a time for some reason and it's been black and I don't know if that's just because I recently fed her blueberries which I think that is the reason but I'm not quite sure and also when she does go it seems somewhat liquidy and also her calcium deposits are more than the actual fecal matter itself so I'm kind of curious as to what might be going on is it just that I need to feed her more or what thanks anybody that helps in advanced. By the way she is about 14 in long including tail and she's in a 40-gallon tank which I know I need to upgrade.

It's possible the blueberries upset her stomach. I've seen that happen with berries. I would remove them from the diet for a while and see if that helps. By calcium deposits do you mean the white urate that comes out along with the poop? I'd make some diet adjustments and see if that helps over the next couple of weeks.

Yes i have taken the blue berries out of her tank and have not given her any at all.
